Can't be too careful. It's a VERY deep breaststroke field. Couple of National Teamers in there (Spencer, Wanland, Carlson). Catherine Meili from Columbia is swimming out of her mind. Ashley Danner has only rested a bit this year, already sub-minute. Sogar looked very good in the relay, as did Ejdervik (who could be an Olympian for Sweden). Carlson is capable of ripping off a 57 too.
Larson is still the favorite, point is I wouldn't mess around too much in prelims if I were her. That's a dangerous game to play in a rhythm stroke like breaststroke, for a still relatively inexperienced swimmer. She's lucky enough to be in the last heat though, so I guess that works in her favor.
She doesn't exactly have a ton of swims in this meet, so overall fatigue shouldn't be a huge problem.
